I don't know that JBJ isn't better or worse than other outfielders, that's why I use the stats. How is it arrogant to defend WAR? I am willing to admit that something else might be right over my own opinion, and that I am probably wrong.
What do you think the margin of error for your eyes is?
If the stats support your opinion, then you say, I already knew that and don't need stats to tell me what I already knew. If the stats don't support your opinion, then the stat must be flawed or useless.
I asked the question before and got crickets. Have you ever changed your opinion on something based on what the analytics told you? No, because you think your opinion can't possibly be wrong. But maybe, just maybe, you are wrong. The eyes will lie.
